IMPROVEMENT IN WATER-METERS.

The Schedule referred to in these Letters Patent'and maklngpart of the same.

To all fwwm it may concern Be it known that we,'A. W'. ALMQvIs'r and F. W. OFELDT, of the city, county,.and State of' NewYork, have invented a new and useful Improvement in Water- Meters; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use-the same, reference being had to the accompanying drawings, forming a part of this spcciiication.

Figure 1 is an edge view of our improved watermeter.

Figure 2 is a vertical central section of the same, taken through the line a: fr., g. 3.

Figure 3 is a side view of the same.

Figure 4 is a detail view of the registering-device.

Figure 5 is a detail face view of the register-dial plate.

Figure 6 is a detail sectional view ofthe supply and discharging-cock. A.

Figure 7 is a detail front view of the same.

Similar letters of reference indicate corresponding parts.

Our invention has for its object to furnish an improved 4water or gas-meter, simple in construction, which may be constructed at a comparatively small expense, and which will work accurately under a small pressure or head of water; and

It consists in the construction and combination of the various parts, as hereinafter more fully described.

A is the body of' the meter, which is made in two parts, provided with flanges a', by which they are securely bolted' together, as shown in figs. l and 3, and which may be made of various sizes, according to the amount of water or gas required.

B is the diaphragm, which is made of India rubber or other suitable liexible material, and the edges of which are clamped and secured between the flanges a of the parts of the body A, and serve as packing be tween said flanges. The diaphragm B, we prefer to make double, to receive the oscillating arm or frame C between, to preserve the said arm or frame from the corrosive action of the water.

C is an arm, the lower part of which is made broad, or which may be made in the form of an elastic framework, and the upper end of which is rigidly attached to the rock-shaft D.

The shaft D works in bearings formed upon or attached to the upper edge of the body A of the meter.

yThe upper end or' the arm C is allowed to move freely, and at the same time the upper part ofthe meter is made water-tight by means of a ring, E, surrounding the upper part of the said arm C, clamped between the parts of the body A, and which holds the diaphragm B pressed closely against the sides of said body A, as shown in iig. .3.

To one end of the shaft D, or to the upper part of the rigid arm J, is attached the upper end of a spring,

F, the lower end of which is connected with an arm'br lever, G, attached to the,valve H or" the cock 1, Aso that the lsaid valve may be operated by the elasticity of said spring F, as the shaft D is rocked by the oscillation of the arm (l, caused by the pressure of the water upon the diaphragm B. The' lower end of the spring F may be attached to the lever G, either above the centre of the cock I, or to an extension of the lever G below the said centre.

The cock I is constructed somewhat similar to an ordinary four-way cock, and the form of which is immaterial, so long as it is constructed with two sets of inlet and outlet-orifices, each set acting independently of the other, and each set being connected with the interior of the body A of the meter upon opposite sides of the diaphragm B.

J is an arm, rigidly attached to the end of the shaft D, and upon the lower end of which is formed a curved or arched cross-head, K, having its centre in the axis of the shaft D.

The arched cross-head K is provided with a iange, 7c', the middle part of which is out away or notched, as shown in' iig. 1, to allow the pin or arm oi' the lever G to pass from the one side to the other of said flange la when released by passing the end of the said flange. The said iianged cross-head K thus acts as a stop, to prevent the valve H from being moved by the action of the spring F before the desired amount of water has entered the body A of the meter. rfhe spring F, in combination with the arm J, provided with the flanged cross-head K, may be used to operate similarly on a sliding valve, or on one otherwise constructed.

In using the meter, the water is introduced through the supply-pipe L into the cock I, through which it passes, when .the apparatus is in the position shown in tig. l, in the direction ofthe arrows l, through the pipe .Minto the body A of the meter, upon the left-hand side of the diaphragm B.

As the water iows in, it presses the diaphragm B and arm O towards the right-hand side of the meter, until the desired amount of water has entered, at which point the pin of the arm or lever G passes the lefthand end of the cross-head K, and is thrown, by the elasticity of the spring F, through the notch in the centre of the flange' It', changing the position of the valve H so that the water may tlow out through the pipes M and N at the same time that the water enters the body A ofthe meter, at the right-hand side of the diaphragm B, through the pipes Lland O, and so on continuously.

The number of times, the meter has been filled, or the amount of water that has passed through it, is

registered by a series of gear-wheels, P, each of which has exactly the same number of teeth, and each succeeding one of which is operated by a single tooth or pin attached to the next preceding one, so that each Vsucceeding wheel may be revolved through the space of one tooth at each revolution of the preceding Wheel,

the rst Wheel of the series being operated by a single or double 'paWl connected With the rock-shaft D.

The teeth of the series. of wheels I are numbered upon .their outer sides, which numbers are seen through small holes in the dial-plate Q', by which the said wheels are` covered. For convenience, We prefer to make each Wheel with ten teeth, sothat the numbers, when read off, may stand in the decimal order, as tens, hundreds, thousands, dto.

It should be observed that the operating-parts of the meter should be covered with a casing, or boX, to protect them from accidental injury.

Having thus described our invention,

What We claim as new, and desire to secure by Letters Patent, is

1. The combinationv of the flexible diaphragm B, oscillating arm or frame C, and rock-shaft D, with the rigid arm J, provided with an arched and ang'ed crosshead, K, and the spring F, substantially as herein shown and described, and for the purpose set forth.

2. The combination of` all the parts, as enumerated in the irst claim, with the lever G and the valve H of the eock I, substantialiy as herein shown and described, and for the purpose set forth.

3. The combination of the rigid arm J constructed as described, spring F, and lever G, with the rock-shaft D and valve H of the cock I, substantially as herein shown and described, and for the purpose set forth.

4. The combination of the ring E with the flexible diaphragm B, arm or frame O, and body A'ofithe'meter, substantially as herein shown and described, and for the purpose set forth.Y

The above specification of our invention signed by us, this 8th day of AJ une, 1868.
